broad. Spores polygonal, pale orange, 13 to 15 ?* diameter. 

 Teleutospores roundish or oblong, occasionally grouped around 

 those of the peridia, confluent on the peduncles, tkc, generally 

 covered by the epidermis at the border, black. Spores raised 

 upon a pedicel gradually dilating upwards and passing into the 

 lower spore-cell, 50 to 63 ii long. Lower spore-cell oblong, com- 

 pressed (laterally dilated to about 18?*), about 29 to 33 it long, 

 lorown ; upper spore-cell wider, almost globular, quadrate or rec- 

 tangular, with much-enlarged apex, which is blackish-brown, 20 

 to 25 7L wide and 23 to 30 u long. Upon Goodenia geiiimdata, 

 Tanunda ; October 29, 1887.

Uromyces digitatus, Winter; Revue Mycologique, October, 

 1886. Acervulus solitary, snowy-white, minute, veiled by the 

 finally cleft epiderm, placed in the centre of a black rotund or 

 orbicular, determinate macula, bounded by a very narrow fuscous 

 line, about -5 to 1 mm. diameter. Uredospores numerous, ovate 

 or elliptical, golden-brown, densely verrucose, with membrane at 

 the apex sometimes a little thickened, 32 to 35 u long and 20 to 

 25 u thick, supported by a hyaline very fragile stipe. Teleuto- 

 spores cuneate-oblong, on a long persistent hyaline stipe, atten- 

 uate at the apex, very much thickened, and bearing three to six 

 digitiform erect or divaricate, often recurved, obtuse processes, at 

 first golden, at length through pale to hyaline, 50 to 60 u long 

 and 14 to 18 u thick. On living leaves of Acacia notabilisj 

 near Gawler, July 1885.

Dimerosporium Ludwigiaxum, Sacc. Hedwigia XXYIIL, p. 

 127. Mycelial macul?e amphigenous, dilutely fuliginous, scarcely 

 determinate, appressed ; perithelia here and there crowded, globu- 

 lar, astomous, superficial, 75 ii diameter, opaquely fuliginous ; 

 hyph^e radiating, concolorous, septulate, unequal, laxly interwoven, 

 appressed, girt at the base ; asci broadly elevate-fusiform, some- 

 what obtuse at the apices, very shortly stipitate, 25 to 28 x 9 to 

 10 u, spuriously paraphysate, octosporous ; sporidia distichous 

 shortly fusiform, uniseptate, not constricted, 10 to 12 x 3 u, 

 hyaline. On wilted leaves of Lagenophora Billardieri, Mount 

 Lofty. Allied to D. venturioides, Sacca. and Berla, from which it 

 differs by the appressed hyphse, by the black contexture of the 

 perithecium, by the perfectly hyaline sporidia, kc.
